Layer-selective proximity symmetry breaking enables anomalous and nonlinear Hall responses in 1H-Nb X 2 (X = S, Se, Te)
The episode discusses a paper showing how layer-selective magnetic proximity symmetry breaking enables anomalous and nonlinear Hall responses in 1H-NbX2 materials. The authors found that an orthogonal two-sided exchange configuration allows for independent tuning of linear and nonlinear Hall effects via geometric control, providing a blueprint for designing materials with specific topological signatures.
